Brit.

/ə(ʊ)ˈsɛlə/,

/ɒˈsɛlə/, U.S.

/oʊˈsɛlər/

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin ocellus , -ar suffix¹.

Etymology: < classical Latin ocellus ocellus n. + -ar suffix¹. With sense 1 compare French ocellaire (1845 in this sense; 1838 in sense ‘marked with round patches’). In sense 2 after German ocellar (H. Rosenbusch Mikroskopische Physiographie der Mineralien u. Gesteine (ed. 2, 1887) II. 635).

1. Zoology. Of or relating to an ocellus or ocelli.

1872 Amer. Naturalist 6 600 The perfect insect is honey yellow, except the eyes, ocelli, and sometimes the ocellar space, which are black.

1895 New Eng. Mag. Apr. 174/2 The caterpillar had simple eyes, the chrysalis an ocellar ribband.

1975 Nature 18 Dec. 604/1 A cut then serves to remove the ocellus and a length of ocellar nerve.

1999 Proc. National Acad. Sci. U.S.A. 96 11900/1 By grafting, we have artificially generated homeotic ribbonworms of the species Lineus ruber with a duplicated ocellar region replacing the postocellar region anterior to the brain.

2. Geology. Having or designating a structure (of igneous rocks) in which minute crystals of one mineral are arranged in radiating aggregations round larger crystals of another mineral.

1941 Science 22 Aug. 183/1 John C. Haff, Colorado School of Mines, will study ocellar structure in lamprophyric dikes and alkaline extrusives.

1988 Geol. Mag. 125 287 The total thickness of ocellar komatiite flows ranges from 5 to 60m.
